wArER-cLosEr-rANK VALVE.

Application filed September 1.0, 1921.. Serial No. 499,709.

To all whom it may concern:

Be it known that I, JosnPH H. SAVILL, a citizen of the United States, residing in Camden, county of Camden, State of New Jersey, have invented certain Improvements in lVater-Closet-Tank Valves, of which the following is a specification.

My invention relates to certain improvements in valves for holding the water in the tank of a water closet or similar apparatus where a body of water is to be held and where it is to be discharged with considerable fiow, the valve being closed after a given amount of water has been discharged.

The object of my invention is to provide a mechanical means for holding the valve in. its raised position, said means being controlled by the flow of water from the tank into the discharge pipe, so that when the flow of water decreases the meanswill allow the valve to drop and close the flow of water from the tank' The after flow, which is used to fill the bowl, passes through the overflow pipe from a separate passage, not

' shown.

In the accompanying drawings:

Figure 1, is a perspective view of my improved water closet tank valve, showing the parts in a closed position;

Fig. 2, is a sectional view of a water closet tank with the valve in a closed position;

Fig. 3, is a view similar to Fig. 2, with the valve in an open position, and illustrates the water flowing from the tank through the pipe leading to the water closet bowl, and

Fig. 1 is a view of a modification of the valve.

1 is the tank, 2 is a pipe which extends from the tank to the water closet bowl, and this pipe is connected to a valve structure 8 located within the tank. The structure has a screw threaded portion 4 which extends through an opening in the bottom of the tank and is held by a nut 5 in the ordinary manner. The valve structure has an annular seat 4P on which rests the valve 5, which in the present instance is made of metal, and both the seat and the under side of the valve are ground to fit. 6 is an overfiow pipe screwed into an extension 7 of the valve structure, so that should the water level in the tank become too high, the water will pass through this pipe 6 down into the pipe 2 to the water closet bowl, and in the present instance the water that flows after the tank has been discharged to fill the bowl to the proper level to form a seal, flows through this pipe in the ordinary manner. Mounted on the valve structure 3 is a casing 8 closed at the top and at opposite sides 9, and has cars 10 which are secured to lugs 11 on the valve structure by screws 12. Pivoted at each end of the casing are gates 13, mounted on pivot bars 14 inthe present instance, so as to swing freely within the casing when the valve is raised. The valve 5 has a stem 15 which extends through a bearing 16 in the casing 8 and is attached to the ball chain 17, so that when it is desired to flush the bowl of the water closet, the chain 17 is pulled, which lifts the valve 5 off its seat 4, and the inrush of water to the outlet pipe 2 causes the gates 13 to be forced under the valve 5, and as the bearin against the valve is close to the pivots 14,.t ey will hold the valve in a raised position against its weight while the water is passing freely through the casing and into the pipe 2. lVhen the water reaches a certain level, and the speed of the outrushing water ceases to a certain extent, then the gates, due to the weight of the valve, gradually close and the valve will finally seat itself and prevent further outflow of water. The gates 13 will then hang in the position illustrated in Fig. 2, as there is no tendency of the water to move the gates from this position. In some instances, the valve may be provided with a rubber face 5 as shown in Fig. 4, the face being formed to fit the conical portion of the valve seat, but I find in the majority of cases that a fiat valve fitting against a ground seat is preferable.

I claim:

1. A water closet tank valve, comprising a valve structure having an opening for the flow of water, a valve seat on said structure, a casing having a closed top and sides and pivotally mounted gates at the ends, and a valve carried in said casing and slidable therein, said casing being detachably secured to said valve structure, to permit the removal of the casing and valve to obtain access to said valve seat.

2. A water closet tank valve comprising a valve structure having an opening for the flow of water, a valve seat on said structure; a casing having a closed top and sides and pivotally mounted gates at the ends; and a valve removably mounted within the casing and slidable therein, said casing being detachably secured to said valve structure to permit the removal of the casing to obtain closed sides having laterally extending ears; access to said valve seat and to permit the a valve carried in said. casing and slidable 10 removal'of the valve from the casing. therein; and fastening means engaging said 3. A Water closet tank valve comprising laterally extending ears for detachably se- 7 a valve structure having an opening for the curing said casing to the valve structure flow of Water; a valve seat on said structure; to permit the removal of the casing and a casing having a. closed top and sides and valve to obtain access to said valve seat.

pivotally mounted gates at the ends, said JOSEPH H. SAVILL.
